The Biggest Animals Kingdom and in The World | Edible Frog | Edible Frog Classification and EvolutionThe Edible Frog is a species of Frog found across Europe that is also known as the Common Water Frog and the Green Frog. The Edible Frog is a fertile hybrid of two other European Frogs, the Pool Frog and the Marsh Frog, that bred when populations where isolated close to one another during the ice ages. The scientific name of the Edible Frog means both "mud" and "guardian" as they are known to never stray far from water, almost guarding the muddy banks.

The Edible Frog is a medium sized Frog growing to around 9cm in length. Adult Edible Frogs are mainly green in colour with light patches of brown on their backs, yellow eyes and a white underside, covered in a few dark spots, Male Edible Frogs also have vocal sacs on the outside of their cheeks and extra skin patches on their feet, both of which are primarily for mating. Edible Frog Distribution and Habitat, The Edible Frog is found across central Europe and as far north as Germany and Estonia. Southern populations of the Edible Frog are found from Croatia, through northern Italy and into the south of France. There are also isolated populations in Sweden and Bulgaria which are thought to have migrated from the countries nearby. Edible Frogs spend all of their time either in or very close to water and are most commonly found in calmer parts of rivers and streams, where there is a slow but constant flow of fresh water.

Unlike many other species of Frog, the Edible Frog is a diurnal animal and is therefore most active during the day. Edible Frogs spend a large portion of their time sitting motionless on the muddy banks where they are perfectly camouflaged by their skin colour. Edible Frog Reproduction and Life Cycles The breeding season for Edible Frogs begins during March and generally lasts for a couple of months. Edible Frogs reach sexual maturity at the age of two and can live until they are 15 years old.

Adult Edible Frogs are carnivorous animals, surviving only by eating other animals. Edible Frogs hunt for their food during the day and can be seen catching food in ponds, and even on land. There are even reports of Edible Frogs venturing up to 500 meters away from water in their quest for nutrition. . Snakes, Owls and water-dwelling Birds are the main predators of the Edible Frog, along with Humans who commonly eat them. Edible Frogs will jump into the water and hide if they sense approaching danger, and will make a loud screeching sound if caught. Edible Frog populations are also under threat from habitat destruction mainly caused by deforestation and water pollution.

of the Edible Frog's scientific name indicates that the species is made up of chromosomes that have been stolen from other species. The esculentus part of the Edible Frog's scientific name is Latin for edible as this species is one of the most commonly eaten Frog species in the world. Edible Frog Relationship with Humans, As it's name suggests, the Edible Frog is used as a food source by people across the continent, although they are most commonly eaten in France where Frog's legs are often served as a national dish.
